This study demonstrates how new diseases of intermediate virulence have an evolutionary advantage. This can also help explain why a disease like COVID-19 has affected so many people. @OxyEvo

Paleontologists have recently discovered fossils from 3 new walrus species near Orange County. One of which has semi-tusks that helps show how walruses evolved to have tusks @OxyEvo

Here's an interesting article about the discovery of the remains of Denny- a Neanderthal and Denisovan mix @OxyEvo

This research suggests that species don't need to have completely separate genomes, but they can have intermediate stages with some genomic overlap and still be distinct from one another @OxyEvo

The separation of these species could be very useful with the conservation of the penguins! @OxyEvo

Scientists are now saying that Gentoo penguins should be classified as four separate species as they no longer interbreed with one another @OxyEvo

The giant mola fish has an extremely high fecundity rate. It can produce up to 300 million eggs in a season! @OxyEvo

The birds-of-paradise in Papua New Guinea have high levels of sexual dimorphism and are very interesting to look at! @OxyEvo

Molecular phylogenies have been very useful in learning more about HIV. Phylogenies will probably also play a big role in learning more about the evolution of COVID-19. @OxyEvo

The mortality rate for babies is much higher when they are either over or under-weight, and mortality rate is lowest when babies weigh the average weight. This is an example of purifying selection. @OxyEvo

Pitcher plant mosquitoes are starting to go into hibernation later since climate change has created a longer growing season @OxyEvo

Marsupials serve as an example of adaptive radiation. It seems pretty common for this diversification to take place on isolated islands. @OxyEvo

An example of disruptive selection where dark and light colored oysters have a camouflage advantage over medium colored oysters to avoid predators @OxyEvo

[Grace Hildner @ghildner_oxyevo]

Interesting article that suggests that mammals and other animals share the same gene that allows for regrowth of neurons, but that the pathway for mammals is turned off. I wonder why this pathway is inactive only in mammals. @OxyEvo

Alike sickle cell anemia, having one copy of the gene that causes cystic fibrosis can be beneficial for humans. This is an example of why deleterious genes persist in populations @OxyEvo https://t.co/Duyu98EF7d

An example of how inbreeding poodles has created a genetic bottleneck with very little diversity in the population ⁦@OxyEvo⁩ https://t.co/bevbb1IXHC

Fish have changed their feeding behaviors and body shapes due to a dam implemented in the Tocantins River @OxyEvo

Lactose intolerance didn't last long for some Europeans. Study shows this evolutionary change was much quicker than most other transformations in humans. @OxyEvo
